This past weekend, Sen. Patrick Leahy led a special congressional delegation to Cuba. It’s part of an effort to normalize relations between the two countries – relations that were severed in 1961 when Fidel Castro came to power. Leahy’s was the first congressional delegation visit since President Obama announced his intentions last month of ending the current restrictions between the United States and Cuba.

President Obama's move to normalize relations with Cuba will test a theory that has been popular for years in Democratic circles, and a few Republican ones too. The Castro government doesn't fear the embargo and interminable hostilities with the United States; it has thrived on them, so the thinking goes. What worries the island's control-minded leaders far more is change.

This week, as the Nobel Peace Prize was formally handed to a teenage Pakistani activist and an Indian child-rights campaigner, a Chinese group issued an alternate award to the retired Cuban leader, long regarded by Western counterparts as a tyrant and Cold War nemesis.

Let’s hand it to the U.S. government: At least this disastrous attempt to overthrow the Castro brothers did not almost lead to nuclear annihilation. But its impact on activists around the world who use digital tools to organize against repressive regimes feels devastating enough.

For years, American outreach to Cuba came in many forms: mafiosos, poison-drenched wetsuits, toxic cigars. But today we learned of a new tactic in the campaign to undercut the Castro regime: a stealth effort by the U.S. government's humanitarian aid agency to create a Cuban version of Twitter.

When Fernando Gonzalez walks out of an Arizona prison next week, the "Cuban Five" will be down to three. Intelligence agents in the employ of Fidel Castro's Cuba, they were arrested in the United States in 1998 and given terms ranging from 15 years to consecutive life sentences on charges including conspiracy and failure to register as foreign agents.
